Not so many years ago, it looked like Robert Downey Jr. was headed toward another tragic Hollywood fall from grace. That now feels like ages ago, as the Oscar-nominated star continues to make blockbuster after blockbuster. Over the weekend, RDJ was spotted in costume on the set of Due Date, a comedy directed by The Hangover helmer Todd Phillips and co-starring Zach Galifianakis and Jamie Foxx. Of course, Robert’s new Sherlock Holmes opens Christmas Day.
